In order to discard at this stage uncontrolled \"collateral\" positive or negative technology influence, we can assume that social good does not come as a side effect when researching certain fields and developing technologies. Even more: if we do not address directly, measure and intentionally promote and control social good, we can cause more harm than good. Therefore, it is of paramount importance to define what we mean when we say \"NLP for Social Good\", what aspects of peoples' lives are improved by NLP4SG and how, and what suitable strategies are to promote and measure the impact of technological solutions related to NLP. However, so far, there is no clear picture of what areas are targeted by NLP4SG, who are the actors, which are the main scenarios and what are the topics that have been left aside. In this paper, we discuss what NLP for social good (NLP4SG) is, and how we can promote the development of more socially positive technologies. The contribution of this paper is twofold: (i) we offer a working definition of NLP4SG and related concepts that can serve as a first orientation in the field;",

In the analysis presented in this paper, we draw upon Shi et al. 2020to compose an adapted list of NLP4SG areas, keeping agriculture, education, environmental sustainability, healthcare, public safety and transportation. We exclude \"social care and urban planning\", as they may refer to different aspects, and we rephrase \"combating information manipulation\" as \"media corrupted communication\" because we want to include not only fake news, but also abusive language. Finally, to tackle specific NLP health-related issues, we extend the list by \"language disorders\". Consider the first column of Table 1 for the list of areas that we take into account.",

Community involvement assures integration and inclusiveness, and it brings more information to the decision on the design of a technology, including knowledge about the contexts in which design decisions are going to have an impact. Furthermore, community involvement adds other perspectives to the design since researchers alone cannot anticipate all the needs of the users and all the possible usages of a technology. Along the same lines, we propose that NLP4SG needs the collaboration of users, activists, minorities, grassroots movements, businesses, non-governmental organizations (NGOs), and social entrepreneurs to achieve a social positive technological development.",

Nevertheless, we do believe that there are certain aspects that need further attention by the community. In what follows, we enumerate these aspects, along with some hints on how to address them. Social good areas with less research. Areas that we identified as producing less NLP for social good publications are, e.g., language disorders, environmental sustainability, urban planning, transportation, and public safety. While it is natural that areas that are less related to language receive less attention in NLP, e.g., transportation, they still offer room for many NLP-applications, which can be tackled with a positive impact. The discussion on which percentage of the research in NLP is appropriate for the different areas still remains open -if it can be resolved at all.",

Although we follow previous research in an attempt to measure NLP4SG by matching keywords of certain areas (Shi et al., 2020), we must be cautious when look-ing at the obtained results: while research in a certain area may imply social good, it may also imply social harm, depending on how a certain technology is going to be used (e.g., a fake news detector may be used to detect, but also to generate fake news). Another analysis over the same data may aid to interpret the achieved results and help to understand whether the approaches of the previous work to address social good areas lead to positive or negative outcomes. With this in mind, and for the sake of a broader analysis of research impact, we include into our consideration other NLP4SG dimensions such as ethics, social good terms and systems of change and collaboration. As a guideline for future research, we may conclude that providing data statements and terms of use for the developed technologies would help preventing potential misuses.",

We believe that it is urgent to actively encourage research to tackle social good areas, and, in particular, also to promote the formation of an interconnected social good community across different academic disciplines.

However, in the course of the presented analysis it became clear that a more systematic method could have revealed more social good NLP related terms. Furthermore, when discussing definitions of social good, we should bear in mind that what is considered to be a \"positive impact\" depends on the context and set of values. For instance, ethical concerns and guidelines are different according to different countries (Hovy and Spruit, 2016; Berberich et al., 2020) and are not absent of social and political interests (Washington and Kuo, 2020). As a consequence, we must acknowledge the limitation of our analysis in this regard since we follow an Eurocentric perspective and focus only on ACL publications.",

NLP-specific ethical aspects formed another perspective of our analysis. We drew upon the ACL Anthology corpus and annotated papers in terms of explicit vs. non-explicit NLP4SG to show a clearer view of the evolution of the field. We identified social good-relevant NLP areas with less research, as well as other social good dimensions that are important to address, and proposed a non-exhaustive list of aspects that need further attention by the community.",
